Engine Block Repair

Prime Machine Inc. Engine department block repair has the capability and knowhow to repair your block professionally.  Our experience of over 40 years on diesel locomotive, oil and gas engine, haul truck, over the road,  and power generation engines given us the relevant skills, knowledge of the realities required in this complex and precision work.

Engine Block Inspection

Engine blocks are chemically washed and cleaned to remove all oil and grease from the block.  Oil passages are cleaned and verified that there are no blockages.

Blocks are laser measured with a laser tracker to verify the block geometry and sizes. This measurement will provide detailed information on block geometry.  This includes sizes and position of the main bores, size and position of cam bores, deck height and flatness, cylinder sizes and position to determine any machining or other dimensional repairs that may be required.  After machining of the large blocks measurements are taken again with the laser tracker and final reports provided on block geometry and sizes.

Large Engine Block Machining

After measurement the repairs are determined and blocks are machined on large precision machines capable of holding all the tolerances required for size and position.
